CentOS下安装Mysql 5.5全过程

一、安装cmake

# 安装所需依赖包

yum -y install gcc libxml2-dev curl screen \

libpng12-dev autoconf libpcre3-dev make bzip2 \

libevent-dev patch libjpeg62-dev libcurl4-openssl-dev \

libfreetype6-dev g++ libtool libncurses5-dev psmisc lrzsz

# 下载文件

wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz

# 编译安装

tar zxvf cmake-2.8.5.tar.gz

cd cmake-2.8.5

./boostarp

make

make install

cmake –version

二、 安装配置mysql

# 下载源文件

wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.17.tar.gz/from/ftp://ftp.ntu.edu.tw/pub/MySQL/

# 或

wget ftp://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.5/mysql-5.5.17.tar.gz

# 创建用户和组

groupadd mysql

useradd -g mysql  -s /usr/sbin/nologin  mysql

# 创建安装目录

mkdir  /usr/local/ mysql

# 创建数据库目录

mkdir  /usr/local/ mysql/data

# 解压

tar -zxvf mysql-5.5.17.tar.gz

cd mysql-5.5.17

# 编译及安装mysql

# cmake编译：

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/usr/local/mysql/data \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_unicode_ci \

-DWITH_READLINE=1 \

-DWITH_SSL=system \

-DWITH_EMBEDDED_SERVER=1 \

-DENABLED_LOCAL_INFILE=1 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_DEBUG=0

# 安装mysql

make && make install

# 复制配置文件

cp support-files/my-medium.cnf  /etc/my.cnf

# 设置权限

chmod +x /usr/local/mysql

chown -R mysql.mysql /usr/local/mysql

chown -R mysql:mysql /usr/local/mysql/data

# 配置开机自启动

cp support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

chkconfig –add mysqld

chkconfg mysqld on

# 修改my.cnf配置

vim /etc/my.cnf

# [mysqld] 添加：

datadir=/usr/local/mysql/data

default-storage-engine=MyISAM

# 以下可选：

log-error =/usr/local/mysql/data/error.log

pid-file = /usr/local/mysql/data/mysql.pid

user = mysql

tmpdir = /tmp

# 初始化数据库

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &

# 启动MySQL

/usr/local/mysql/bin/mysqld_safe –defaults-file=/etc/my.cnf &

或者：

/etc/init.d/mysql start (service mysql start)

# 测试MySQL是否启动

# 1)查看是否有进程mysql

ps -ef | grep mysql

# 2)查看端口是否运行

netstat -tnl | grep 3306

# 3)读取mysql版本信息

/usr/local/mysql/bin/mysqladmin version

# 至此，MySQL安装完成
